I want to know how the spot welding machine controls the welding time and the rest time. Is it controlled by PLC?. Hope expert pointing one or two.
Look at the size of your factory, the general use of time relay on the line, and if it is large, you can control through the PLC, it will become automatic control.
Now the general control is PLC. In addition to time, there are currents, pressures, etc., which are controlled.
